suNnAn-cUr-ronmne momma Application filed September 25, 1922. serial no. 590,265.

To all whom it may concern:

, Beit known that I,"C nsAnn BARBIERI, a subject ofthe Kingof Italy, and a resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in a Sundae-Cup-Forming Machine; and I do hereby declare .thatthe following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and the numerals marked thereon, which form a part of this specification.

This invention relates more particularly to an improved type of a multiple automatic cup forming machine, especially adapted for manuf cturing conical sundae cups and having attachments whereby the formed cups are first adapted to be automati'cally removed from a forming mechanism and delivered into a position to be stacked nested one within the other below retaining means with the folded portions of adjacent cups staggered to permit the formation of astraight stack of cups between suitable guards.

It is an object of this invention to providea machine which will automatically form conical paper sundae cups from prepared blanks and discharge the cups into a conical holder adapted to be rotated each time a cup is received so that the folder portions of the cups will be staggered in order "to permit the, formation of a straight stack of cups instead of a stack wherein the folded portions of the cups registerone with the other to produce a stack which will assume a curved formation and be exceedingly hard- I to handle.

It is also an object. of theinvention to provide a machine adapted to form conical cups from blanks and then push the cups down into a rotatable receiver below resilient retainers which serve to'holdthe cups nested one within the other between suitable guards.

It is a further object of this invention to provide a machine wherein cups formed from blanks are adapted to be delivered over a stacking mechanism and then pushed into said mechanism below retaining members which serve to hold the cups pressed one within the other to prevent the folded portions of said cups from springing the cups out of proper nested relation with one, another.

It is furthermore-an object of this invention to provide a cup receiving mecha nism. havin a cup support adapted to be automatical lowered and 'rotated each time 7 a cup is delivered thereto.

Another object of the invention is to pro-- vide a cup forming machine with an automatic stacking attachment which will deliver a formed cup from tht cup formers into a position to permit the same to be pushed between resilient retainers down into 1 It is also an object of the invention to provide a sundae cup forming machine wherein means are provided for removing a cup from forming means and pushing said cup into position wherein a reciprocating rod is adapted ,to engage the cup at a predetermined time and forcethe same downwardly through a receiving ring below retaining means and into a holder adapted to be lowered a predetermined distance and partially rotated each time a cup is delivered-thereto. -A further object of the invention is to provide a machine adaptedto automatically remove blanks from a magazine, deliver the same properly centered to a forming means to be formed into a cup which is automatically delivered into an automatic stacking attachment whereby the formed cups 'are nested one within the other with the folded portions of the fcups staggered to form aforming; machine, said attachment having taken on line 99 0 means for holding nested cups from springiIig apart as the stacking process takes ace.

Another obg'ect of the invention is to provide a cup forming machine with a stacking attachment operable from the machine and having mechanisms for automatically lowering androtating a cup holder predetermined amounts each time a cup is delivered thereto.

It is an important object ofthis invention to provide an improved multiple cup forming machinewherein each of. the units 'is driven from a common source and is adapted 'to automatically feed blanks 'into a forming mechanism adapted to form cups and crease the folded portion thereof and then remove the formed cups from the forms and automatically stack said-cups in straight stacks with the folded portions of the cups sta gered.

ther and further important/objects of this invention will be. apparent from the disclosures in the drawings and specification. 1 v The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

The entire machine is of the multiple typeimade up of a' pluralit '(lif n y one of the units is illustrated and described.

The drive shaft 1 has a pinion 3 secured thereon and meshing with a large gear 4 supported on a bearing sleeve 5'. Fixed on the sleeve 5 to rotate with the gear ,4; is a,

pinion 6. The pinion 6 me'shes with aJarge gear 7 which drives a cam shaft 8 ithrough a clutch mechanism 9operable' by a control lever 10 pivoted at one end to a bracket 138 and intermediate its ends to a slidable shaft 139 common to all the units. Rotatable upon the cam shaft 8 is a sleeve 11. v A control clutch may be provided for each unit of the machine if desired.

Keyed on the camshaft 8 inside of the machine frame 2 is a gear 12 meshing with a gear 13." The gear 13 is secured on a stub shaft14 which is journalled in bearings at one end of the frame, Secured on the outer end of the shaft 14 is a disk 15 having a roller 16 mounted on the periphery thereof to coact with a four-point Geneva gear 17. The Geneva gear 17 is fined on the outer end of a shaft 18 supported by the machine frame and having a gear 19 keyed thereon. The gear 19 meshes with a pinion 20 fixed on one end of a longitudinal driving shaft 21 supported, in suitable bearings 22 on the machine frame. Fixed on the shaft 21-is a beveled gear 23 which drives a bevel gear'24' wheel 25 around which an endless chain 26 is trained. The chain, 26 is also trained around a smaller sprocket wheel 27 rotatablymounted on a shaft 28 supported in suitable bearings 29. The sprocket wheel 27 has a drive pin 33 thereon which projects into a passage 31 provided in the hub of a clutch hand wheel 30. The hand wheel is also provided with a passage 32 into which a longer pin 34 projects. The pin 34 is fixed on a knob 35 secured on one end of the shaft 28. A drive is imparted from the sprocket wheel '27 to the shaft 28 through the pins 33 and'34 when the hand wheel 30 is engaged with the sprocket wheel pin 33 as illustrated in Figure 23. The clutch hand wheel 30 affords a quick release for the blank feed mechanism of the machine by simply sliding the hand wheel 30 against the knob 35 and out of engagement with the drive pin 33.

The blank feeding mechanism is operated by a small beveled gear 36 fixed on the shaft- 28 and meshing with a larger bevel gear 37. The large bevel gear 37 is-provided with an integral sleeve 38 which is keyed on one end of a shaft 39 journalled in a box section 40 forming a part of the machine frame. One end of the shaft 39 is hollow to receive a slid-able rod or bar 41 having a knobor handie 42 fixed on the outer end thereof. Secured diametrically through the rod 41 is a drive pin 43, the ends of which project through slots 44 provided in the shaft 39 (Figure 24). The slots 44 limit the telescoping movement of the rod 41 inthe shaft 39 whereby the blank feedmechanism may be quickly released in case of emergency. The pin 43 is adapted to coact with a pin 45 to cause rotation of a blank feed reel on which said pin 45 is mounted. The blank feed reel is rotatably supported on the shaft 39 within the box 40 and comprises apair of spaced circular plates or disks 46 connected by bars 47. 1 Supported on one of the reel bars 47 between the disks 46 is a curved blank feed friction pad or block 48 made of rubber or other suitable material. The feed pad-48 extends around only a portion of the periphery of the reel so as to operate upon a paper cup blank to be fed only at a predetermined time.

Mounted on the machine frame is a table 49 having an opening therein, above the box 40, through which the feed reel is adapted to act uponcup blanks which are supportedin a circular magazine 50 mounted on the table 49. above theopening. Supported in a the box section 40 is-a bracket 51 holding a,

pin 52 which projects through the plate opening to afford a support for the stack of cup blanks within the magazine. A air ing arms 55 which are held in lowered position by means of coiled springs 56. Fixed on one end of the upper roller shaft 57 is- Fixed on the shaft 39 adjacent one end of i the feed reel is a cam adapted to coact with a roller 66 supported on one side of a bar 67 having a slot in one end thereof to permit the bar to slide transversely on the shaft 39. The other end of the bar 67 is pivoted to one end of a crank 68 fixed on a rocker shaft 69 supported by brackets 70. Secured on the rocker shaft 69 are a pair of pusher arms 71 which operate together to engage a cup blank after it passes between the feed rollers 53 and 54. The upper ends or tips of the pusher arms 71 operate in in retracted position. Positioned on the top of-the table 49 are a pair of spaced rollers or stops 74 against which the cup blank is adapted to engage when pushed over the table by the pusher arms 71. Secured on the table 49 bet-ween the stops 74 is a shoe 136 having an enclosed surface 137 up which the advance edge of a blank is adapted to slide.

The shaft 21 is intermittently rotated by the action of the four-point Geneva gear 17 and the cup forming mechanism is driven thereby through the bevel gears 23 and 24. The forming mechanism is mounted on a shaft 78 journalled in bearings 75 and said shaft has the bevel gear 24 fixed on the outer end thereof. Also supported on said forming shaft 78 is a clutch mechanism 76 and same by means of which the forming elements of the various units may all be brought into proper timed relation with the feeding means similar to the arrangement disclosed in my cope'nding application for patent for a multiple automatic folding machine, filed September 10th, 1921, Serial No; 499,614. :The shaft 78 extends toward the front part of the machine and is provided with a pivot pin 79 (Figure 13) which extends therethrough. Mounted on the pivot pin 79 are two gripper holder members 80 adapted to cooperate with each other and each having attached to its outer or forward end a forwardly extending gripper plate 81.

Rotatablymounted on one side of the reciprocating'bar 216 is a roller 218 (Figure 5,) which is adapted to track in a cam groove 219 formed in a cam disk 220'fixed onthe cam shaft 8. Pivoted to the long bell-crank arm 213 is the lower end of a connecting rod or toggle 221. The upper end'of the connecting rod 221 is pivoted to the lower end of a vertical rod or shaft 222. The shaft 222 slidably projects upwardly through an opening in the table 49 and has a collar 223 secured near the upper "end thereof by meansof a set, screw 224. Supported by the collar 223 is a pin 225 on which a beam 226 is fulcrumed intermediate its ends. Pivoted to, one end of the fulcrumed beam 226 'is the upper end of a link 227, the lower'end of which is pivoted to one end of a stationary bracket 228 secured upon the upper end'of a vertical standard or post 229 mounted on the table 49. Pivoted to the other end of the fulcrumed beam 226 is the lower end of an upwardly directed link 230. The upper end of the link 230 supports a pin 231 on which a collar 232 is supported. Projecting through an opening in said collar 232 is the upper end of a cup push rod 233 secured to said collar by a set screw 234. The push rod is slidable in. a guide sleeve 235 integrally formed on the bracket 228. Engagedon the post 229 below the sleeve 235 is a cup stop spring 236 resilientlyheld in stop position by a coiled spring 237 engaged around the post 229.

' For the purpose of manually rotating the cam shaft 8 a hand wheel 238 (Figure 3) is mounted on each end of said cam shaft.

The operation is as follows: 7 The machine is operated by rotating the driving shaft 1 by any suitable driving mechanism whereby the drive is transmitted from the pinion 3, gear 4 and pinion 5 to the large gear 7. The clutch control handle 10 is then actuated to throw in the clutch 9 to cause operation of the cup making unit.

A number of similar units are connected to form a multiple machine, each unit of which is provided with a clutch control handle 10 so that the various units may be started by the operation of anyone of said control handles. The operation will be confined to one unit.

The clutch 9 being mounted on the cam shaft 8, causes rotation of said shaft when the clutch is operated; Rotation of the cam shaft 8 causes rotation of the gears 12 and 13 which in turn impart'a drive to the disk 15, the roller 16 of which operates the four-point Geneva gear 17, By means of the meshing gears 19 and 20, the shaft'21 together with the beveled gear '23 is intermittently rotated avquarterof a revolution with each complete revolution of the disk 15. At the same time the cam shaft.

8 by means of the chain 26 and the beveled pinion'36 drives the beveled gear 37 and the blank feeding mechanism which continuously delivers preparedsundae cup blanks of paper to, the cup forming device. A

stack of prepared cup blanks is positioned in the magazine 50 and the delivery of a cup blank from the bottom of the stack is accomplished by means of the rotatable feed reel 46 -47 which carries the friction pad 48. The feed reel is rotated by the beveled gear 37 which rotates the shaft 39 supporting said feed reel. As the feed reel is rotated, the friction pad 48 thereof is moved into contact with the bottom surface of the lowermost cup blank and frictionally slides said lowermost blank from the magazine between the feed rollers 53 and 54. The lowermost blank is thus delivered 'to the feed rollers and the stack of blanks falls by gravity in the magazine resting on the pin 52.

Referring now to Figures 23 and 24, itwill be noted that if at any time it becomes necessary or it is desired to stop the blank feeding mechanism without stopping the entire machine, the hand wheel 30 is manually pushed outwardly from the position shown in Figure'23 against the knob 35 thereby disengagingjthe pin 33 on the sprocket wheel 27 thereby causing said sprocket wheel 27' to idle on the shaft 28 whereby the blank feeding mechanism is stopped.

Another arrangementis provided for stop-- ping the blank feed mechanism and this is accomplished by manually pulling the rod 41 by means of the knob or handle 42 outwardly with' respect to the shaft 39 thus moving the driving pin 43 out of driving engagement with the pin 45 on thefeed reel 4647. The manual feed stop mechanisms are conveniently positioned so that the blank feed mechanism may be readily stopped from the front or from the back of the machine.

With the pin 43 and'the hand wheel 30 in driving ositions, as illustrated in Figures 24 an 23,. a cup blank is fed from .the magazine between the auxiliary feed operation takes place, the spring i 'the forming of the,cup as'described, the projection 241 (Figure 18) comes into en-' member 154. cause the lever 152 to lower 136 and against the stops74. As the pusher.

arms 71. push the blank against the stops -74, the positioning heads-99 on the arms 97 are actuated in the table slots 98 and move inwardly to, cause the 'pins' 100 to further position and centerthe cup blank on the table in the field of operation of the cup forming mechanism. The positioning arms,97 are carried by the arm 102 secured on the shaft 103. The shaft 103is rocked or partially rotated by means of the bellcrank 105, the roller 109 of which coacts with the cam .110 mounted on the cam shaft 8'.

The gripper. plates 81 are separated during the time the cup blank is being positioned; this separation is accomplished by raising the forming member 83 about its pivot point 87 by means of the cam 116 which acts onthe roller"115 to raisethe' When the point 240 of the cam116 reaches the roller 115, .the forming member 83 is permitted to be gradually loweredand the gripping plates are caused'to close by the spring 82 to engage the centered cup blank therebetween. e

The action of the disk 15 and its roller 16 upon the Geneva gear 17 now commences and the gripping plates 81 are thus rotatedthrough a half revolution to fold the blank intd the form of a conical sundae cup. After gagement' with the roller 115 to raise the forming member 83 and separate the gripping plates. \Vhile the gripping plates are being separated by the action of the cam projection 241, the cam 165 on the cam shaft 8 actuates the bar 161 and the crank arm 160. whereby the shaftv 153 and the bracket amt-advance the arched arm 146 from its mnerfmost'positiolt a short distance to cause :thmip engaging bar 148 to engage in the formedcup to center the cup and advance the same a slight distance away from the former 83 andthe gripping plates 81. Vith the formed cup partially removed from the .forming mechanisms, the continued rotation 79 of the cam 116 brings one arm of the bellcrank 183 into engagement with the curved shoe 131 of the bar 130 carried by the bar 118\- Asthe bell-crank arm 132 passes the shoe 131, said shoe is adapted to suddenly drop off of said arm thereby permitting the compressed spring 82 and the compressed presser arm spring 129 to clamp the folded portions of, the cup to crease the same.

The forming member 83 and the presser arm 126 act to clamp one side of the folded por-. tion of the cup while the other side of said folded portion is clamped between the forming member and-the table 49 The'cup id thus formed and creased ready to be delivered-to the stacking attachment.

The continued rotation of the cam 165 continues to swing the lever l52 oiitwardly outwardly into the position shown in F ig ure 12. The formed cup 166 is thus. transferred from the forming mechanisms over the table 49 into a position over the stacking mechanism. cross bar 148. When the cup is advanced over the stacking mechanism'thepusher rod 233 is ele-I vatedto permit the cup to be pushedagainst the light plate spring236. -As t-he cup is pushed against the spring 236, the rodfl233 is lowered through the guide fork 150 011 the arched arm 146.

The roller 218 acting in the cam groove 219 causes the bar 216' to actuate the bellcrank 212-213 (Figure 5) whereby the connecting rod 221 tends to pull the shaft 222 downwardly. 226 is thus lowered causing the-link 230 to force the pusher rod 233 downwardly into the apex of the cup166 thereby pushing the cup from the position illustrated in Figure 12 down through the plate opening'168' whereby the cups are stacked with the. foldedr.-.,
